SPECIFICATION forming part of Letters Patent No. 300,376, date time 17, 188%.

Application filed January til, 1884. (No model.)

To (LZZ whom it 17mg concern..-

Be it known that 1, WILLIAM J. LANE, of Poughkeepsie, in the county of Dutchess and State of Xew York. have invented a new and useful Improvement in Steam-Heaters; and I do hereby declare that the following is a full, clear, and exact description of the same.

.Hy invention relates to steam-heaters, and is principally designed for the heating of houses.

The object of the invention is to provide an cfiicient durable apparatus with less cost than the ordinary expense.

My invention consists of certain details of construction fully explained hereinafter, and illustrated in the accompanying drawings, in which- Figure 1 is a front elevation; Fig. 2, a side elevation. Fig. 3 is a vertical section taken through line .1? of Fig. 2. Fig. at is a horizonta-lscction showing the coils and magazine, on line y g of Fig. 1. Fig. 5 is a side view of the outside coil of pipe.

I aim, first, to provide a steam-heater with a brick inclosure and amagazine or fuel-reservoir combined with pipes for the generation of steam. The magazine must necessarily be of metal; but the sheetanctal casing ordinarily used lacks durability by reason of rapid rusting when out of use, and also radiates heat rapidly, and is on these accounts objectionable. To avoid this I use brick walls A, with a top of brick, (1. The bricks which form the top rest upon suitable bars or plates, b. In this top is suspended the reservoir E, made of cast-iron, and of ordinary cylindrical form, excepting that it is enlarged at the upper end, in order that it may be properly suspended in the brick covering. its lower end terminates in suitable relation to the fire-pot O, which is :t'ormcd, preferably, of fire-brick, and supported upon a metal plate, 0, which prevents any comniuinication between the ash-pit and the lire-chamber, excepting through the firepot. A grate, 1'), is supported upon a bar, (I, set in the brickwork and extending across the ash-pit. A suitable place is left around the magazine for the reception of the pipes and for the circulation of the products of combustion. The brick-work may be rectangular in form, and this is the preferred form, since with 1t the pipes may be made of straight pieces connected by screw-joints of ordinary gas-fittings. The magazine is filled in the top,

and is provided with a cover, 0, tit-ted as tightly as possible, and preferably made of brass or some non-corrodible metal. This combination of the iron magazine and the brickwork constitutes a cheap magazine heater with an effective non'conducting case. ithin the fire-chamber surrounding the magazine I locate pipes g 71. These pipes may be sections of ordinary gas or water pipes united by malleable-iron or other connections,1. As shown in Fig. l, pipe G is carried through the brick "wall and communicates with the waterreservoir outside. Pipe g connects with the end of this pipe, and the pipe 71 is located just within the pipe g, and connected to the pipe G by a T. These pipes are carried around the magazine in coils or turns, rising one above the other, as shown in Fig. fillhe upperinost of the series are connected to the pipe G in the manner shown in Fig. i, which pipe is carried through the wall of the reservoir.

Each completed turn in the form shown is eomposed of tour pieces, all of which are inclined upward at a uniform grade or angle, so as to terminate just above the first of its series. More or less than two sets of pipes maybe used, and the coils may be of any convenient number to suit the size of the apparatus.

The reservoir or drum is shown in Figs. 2 and 3 at F. It consists of pipe of suitable diameter, with heads j screwed on in the ordinary manner. The pipe G attached to it at the botton'i of the reservoir .or drum. The upper pipe, (3, is connected with the drum near the center. The steam-pipe i. from the upper part conducts the steam to the radiators, and the watcrof condensation is returned by pipe 7., entering the drum, preferably on the line with the entrance of the pipe G. \Vhen a sufiicicntly largo steam-pipe is used, the returirpipe 7: may be omitted and a single pipe, i, perform the double oilice. The drum or reservoir F is supplied with the ordinary appliance, of which H is a water-gage, I a pressure gage, and J a safety-valve. The smoke-passage is carried from the combustionehamber into an extension of the brick-work A, and in this extension a check-door, g,opcns outward from the smoke passage. Fig. 1

showsa smoke-pipe, 1, leading from this passage to the chimney.

A damper-regulator is shown at K. It consists of a lever, m, having one end connected to the draft-door a and the other to the checkdoor g by similar chains. A weight is set at the proper point, according to the amount of the boiling water has less specific gravity than that of the reservoir F, the water in the coils will move rapidly around its circuit from the lower part of the drum through the pipe G and the coils,and through the pipe G back into the drum, continuously Rapid circulation of water washes the interior and frees it from all pipes, I have provided openings having metal caps p p.

I claim as my invention- 1. In a steam-heating apparatus, a drum or reservoir, pipes G G, and a series of coils composed of straight sections and curved connections around the magazine, substantially as described.

2. In a steam-heater, and in combination, a magazine, the pipes G- G, and the coils or turns 9 h, said pipes being united above and below, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
